Phexx is a non-hormonal, bioadhesive gel that works by maintaining an acidic vaginal pH and decreasing sperm motility. In clinical studies, Phexx was proven effective and safe.

Watch this video to see instructions for the correct use of Phexx. You can also share this video with your patients so they understand how to use Phexx.

Read about the AMPOWER Clinical Trial, a Phase 3, single-arm, open-label trial that demonstrated the safety and effectiveness of Phexx.

Phexx offers a non-hormonal side effect profile3

Phexx is non-systemic, and systemic exposure is not expected to lead to safety concerns.3

The majority of adverse reactions in clinical trials (≥10%) were mild, and few led to discontinuation:

  • Vulvovaginal burning sensation (18.0%)
  • Vulvovaginal pruritus (14.5%)
  • Only 1.6% discontinued due to adverse reactions
  • Two subjects discontinued due to male partner symptoms, and less than 10% of male partners reported local discomfort

Phexx can meet the personal needs of women

Breastfeeding3

Phexx has not been studied in breastfeeding women; however, Phexx works locally and may be an appropriate choice for breastfeeding women.

Concomitant Use3

Phexx may be used with latex, polyurethane, and polyisoprene condoms, as well as vaginal diaphragms. Avoid Phexx use with vaginal rings.

The box may be black, but Phexx does not have a black box warning. The ingredients are nontoxic, making Phexx a suitable option for women who are contraindicated for hormonal contraception.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Few cases (0.36%) of adverse reactions of cystitis, pyelonephritis and other upper urinary tract infection (UTI) have been reported in Phexx clinical studies. Of these, one case of pyelonephritis was considered serious and required hospitalization. Avoid use of Phexx in females with history of recurrent urinary tract infection or urinary tract abnormalities.

ADVERSE REACTIONS

Most common adverse reactions were vulvovaginal burning sensation, pruritus, mycotic infection, genital discomfort (including male partners); urinary tract infection, bacterial vaginosis, vaginal discharge, and dysuria. Patients should consult their healthcare provider for severe or prolonged genital irritation or urinary tract symptoms.

Advise the patient:

  • To discontinue Phexx if they develop a local hypersensitivity reaction.
  • That Phexx does not protect against HIV infection or other sexually transmitted infections.
